Subject: selftests/bpf: Copy runqslower to OUTPUT directory
Patch-mainline: v5.8-rc1
Git-commit: b26d1e2b60284dc9f66ffad9ccd5c5da1100bb4b
References: bsc#1177028
$(OUTPUT)/runqslower makefile target doesn't actually create runqslower
binary in the $(OUTPUT) directory. As lib.mk expects all
TEST_GEN_PROGS_EXTENDED (which runqslower is a part of) to be present in
the OUTPUT directory, this results in an error when running e.g. `make
install`:
rsync: link_stat "tools/testing/selftests/bpf/runqslower" failed: No
such file or directory (2)
Copy the binary into the OUTPUT directory after building it to fix the
error.
Fixes: 3a0d3092a4ed ("selftests/bpf: Build runqslower from selftests")
